Verdict

The call

The clearest difference is price: VisuStruct at Free against JSON Tree's $1.99. VisuStruct also leads on review sentiment (33% vs 0%) and update cadence (every 4 days vs every 3 weeks). JSON Tree's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 17.0). On ads and in-app purchases there is nothing between them.
